Hello,
I need to implement a custom lua function that unfortunately has some latency - say, it reads from disk and returns the data:
With a single call it's bearable but if there is a script like
```
foo();
foo();
foo();
```
then the latency multiplies. Is it possible to recognize that a caller does not really read foo's return value in the script?
The motivation - to batch I/O requests together in that case by returning from the function earlier than the I/O finishes

Best regards,
Roman
